JKMakowka;
Thank you for giving me this linkage.
I can take adavatage of this standard to convice our policy makers that normal flush toilets are not a good symbol of western mordern living style.
best wishes

extract from the SCOPE of the document:

This document is applicable to sanitation systems containing both frontend and backend components that are either manufactured as one package or designed to be integrated as a set of pre-fabricated elements to be assembled in one location without the use of any additional engineering and/or civil engineering structures. This document also applies to individual pre-fabricated backend components that are designed to be integrated with one or more specified frontends that meet relevant national and/or international standards without demanding any additional engineering and/or civil engineering structures. This document is not applicable to sanitation systems constructed in-situ.

I wonder whether this document will be applicable in Africa in the foreseeable future. Unless of course, if BMGF manages to develop and market a 'Reinvented toilet' as successfully as MS Windows.

... and the document is not posted here because ISO/IWA sells it at 195 CHF.

But a word of warning... the website is almost impossible to use on slow internet connections.

P.S.: I thought all works supported by the Gates foundation would be open-access in the future?

Dear BGOODBAUM,
Thank you for posting the valuable information. The work of IWA ISO,ANSI is telling the world that normal flush toilet is not the only one solution of sanitation in China.
FIY. I am very sad that one city of China is planning to spend 20 billion RMB to clean two small rivers.

Fully agree with Chris. I believe participants were sponsored by Gates. Why not invest a small fraction more by making the outcome document available to all?

Dear BGOODBAUM,

This seems very important. Thanks for posting it, but why do you not simply post the draft document? The iso.org link does not lead to such document.

Best wishes,
Chris Canaday

A new International Workshop Agreement (IWA) published by the International Organization for Standardization (ISO), and supported by the American National Standards Institute (ANSI), will serve as the basis for the development of a new international standard for sustainable non-sewered sanitation systems. The IWA signifies progress to enhance efforts in reducing environmental hazards associated with poor toilet sanitation, while meeting individuals’ health and safety needs worldwide, as billions of people live without access to clean and safe toilets.

Entitled Non-sewered sanitation systems — General safety and performance requirements for design and testing, the IWA is available to purchase on the ISO site , with definitions and outline of the document free of charge at www.iso.org/obp . The document will serve as the working draft for new ISO Project Committee 305 , Sustainable non-sewered sanitation systems, which is focused on the development of the International Standard in this area. ANSI, the U.S. member body to ISO, which serves as the ISO PC 305 Secretariat, calls on stakeholders to participate in the committee.

The IWA is significant for progress towards cleaner global sanitation, as it provides a baseline so that relevant reinvented toilet products can be developed, tested, and marketed while the standard is being finalized. It also serves as the first step toward the goal of developing an international standard that will cover safety aspects of next-generation toilets, and will help ensure that treated discharged products pose no user, operator health, or environment risks.

The document is a result of the ISO International Workshop in Singapore this June held by ANSI, with support from the Bill & Melinda Gates Foundation, which fostered discussions to facilitate the development of a globally relevant consensus standard for safer, cleaner reinvented toilets. The event united 65 attendees representing industry, government, academic/research bodies, standards body staff, NGOs, and certification bodies, who collaborated on the IWA publication.

Next-generation toilets, also referred to as sustainable non-sewered systems, are a practical solution to disease and preventable deaths worldwide: The World Health Organization (WHO) estimates that 2.5 billion people have no access to safe, clean toilets, and 1 billion are forced to defecate in the open. Such circumstances are linked to crime and approximately 700,000 preventable child deaths every year.

An international standard in this area is crucial to the health and welfare of billions. By documenting the commonly accepted criteria by which to measure the performance of reinvented toilets, an international standard would enhance efforts to widely manufacture, market, and deploy the technology where it is needed most. Such a standard would be applicable to individual and community sanitation systems that are self-contained, meet defined discharge requirements, and would aim for sustainability.

ANSI encourages stakeholders to access the IWA document via www.iso.org and access definitions and outline of the document (free) at www.iso.org/obp. Read more about the IWA workshop on www.ansi.org/toilets .
